Finite element analysis of anisotropic optical waveguide with arbitrary index profile
(1999-12-01)
This work presents the application of a scalar finite element formulation for Ex (TE-like) modes in anisotropic planar and channel waveguides with diagonal permittivity tensor, diffused in both transversal directions. This ...

Modal analysis of anisotropic diffused-channel waveguide by a scalar finite element method
(Institute of Electrical and Electronics Engineers (IEEE), 1998-09-01)
A procedure to model optical diffused-channel waveguides is presented in this work. The dielectric waveguides present anisotropic refractive indexes which are calculated from the proton concentration. The proton concentration ...

An Interface Strip Preconditioner for Domain Decomposition Methods: Application to Hydrology
(Wiley, 2005-12)
In this paper, the efficiency of a parallelizable preconditioner for domain decomposition methodsin the context of the solution of non-symmetric linear equations arising from discretization of the Saint-Venant equations, ...
An Interface Strip Preconditioner for Domain Decomposition Methods
(IOS Press, 2006-12)
A preconditioner for iterative solution of the interface problem in Schur Complement Domain Decomposition Methods is presented. This preconditioner is based on solving a problem in a narrow strip around the interface. It ...
On sum of squares certificates of non-negativity on a strip
(Elsevier Science, 2021-07)
In Polynomials non-negative on a strip, Murray Marshall proved that every non-negative on the strip can be written as with sums of squares in . In this work, we present a few results concerning this representation in ...
